SNAP-FASTENER SOCKET AND PARTS THEREOF Application filed February 7, 1929. Serial No. 338,063.

This invention relates to improvements in snap fastener sockets and parts thereof. Although intended to be of general application, the invention is of particular importance in the making of snap fastener sockets adapted for use as attaching elements on rugs, carpets1 and in other like situations calling for unusually heavy conditions of service.

One object of the invention is to provide a relatively simple, but strong and effective, stud-retaining element for a snap fastener socket.

A further obj ect of the invention is to provide a housing adapted for use as a means whereby the stud-retaining element may be satisfactorily attached to the article on which the socket is to be used. The housing may comprise a single piece of metal having one part adapted to serve as a seat for the studretaining element, parts adapted to serve as fastening elements whereby the stud-retaining element may be secured in the housing, parts to serve as attaching spurs, and parts adapted to form a thumb-piece whereby the socket may be pressed into engaging relation with a stud.

The improved stud-retaining element may be used as a part of a socket having a different type of housing, and the housing may serve as an attaching element for a different type of stud-retaining element.

A stud-retaining element embodying the features of 'the invention sought to be protected may be madefrom a blank, one appropriate form of which is illustrated in Figs. 1 and 2. This blank may comprise a sheet of metal 20, having a circular opening 21 therein, from which radiate slits 22 dividing the vportion of the blank surrounding the opening into a number of inwardly-directed resilient fingers 23. The outer portion of the blank may be cut to form a plurality of outwardly-directed fingers 24, which may, by any suitable means, be bent, as indicated in Fig. 3, to form a second series of inwardly-directedy fingers, the surfaces of which lie in planes parallel to the planes of the fingers of the first set.

The blank 20 may be cut to appropriate form to produce any desired number of fingers. Preferably, the fingers will be so disposed that those of one series will bridge the gaps between those of the other series, and the fingers of the second series will be bentdown into contact with those of the first series sothat the fingers. of either series will act as reinforcing elements for the fingers of the other. .Either series of fingers may be of such lengt-h as to terminate in and de-I fine the stud-receiving orifice of the iinished socket. Preferably, the lengths of the fingers of both series will be such that they all cooperate to form the stud-receiving orifice, so that 'the fingers of each series will serve as stud-retaining elements and those of either series will serve as reinforcing elements for those of the other series.

to the positions which ,they occupy inthe'.

finished structure as a result of one or more operations acting upon all of y the-fingers simultaneously.

In Figs. 4 and 5 is illustrateda housing readyv to receive the stud-retainingelement.

This housing.,y in the-.form herein disclosed,- comprises a seat 25` for the stud-retaining element, having a circular opening 26 therein of a diameter slightly larger thanthe stud'- receiving opening r21 of the stud-retaining element. Surrounding the seat 25 is a flange or wall .element 27,l preferably of cylindrical form or approximatelyso, fromwhich extend a plurality of fingers 28, 29. rThe fingers 28 may comprise a series of pointed spurs by which the snap fastener socket may be secured to the article toy which it is to be attached. The fingers 29 may be spaced in alternation with the fingers 28 and may be-bent inwardlyl and downwardly so as to serve as securing devices for the stud-retaining element after it has been inserted in the housing against the seat 25. Y

A completed snap fastener socket embodying the features of the invention thusr far described is illustrated in Figs. 6 and 7 in which the stud-retaining, element is indicated as having been securely fastened in the housingby the bendingvinwardly of the fingers 29, and the spurs 28 are-in proper position to be thrust Vthrough the material of the article to which the socket is to be attached, after which they may be turned outwardlyA and downwardly to the positions indicated in Fig. 8.

The above-described socket is adapted to cooperate with a stud of appropriatel form, which maybe fastened in any suitable manner vto the vfloor or to any other object or articleto which it isdesired to secure the article onl which the socket isused. YIn Ffig.'9 is illustrated conventionally, a stud;l to be screwed into the floor forcoop'eration with a socket secured `to the-under Iside of a rig r' or 'c arpet.v y Itlwill be apparent that, if the stud-andl socket are pressed 'towards each other with a sufiicient degree offforce, the stud-willfilrst causethe fingers 23 ofthe socketto be 'flexed' inwardly,J4 and thefiii'gers 23`fwill, in turn,

causethe fingersl to'be'flexedinwareilly As the j st udI movesdnto the socket, the s lingers 28fwill be first'rele'asediby'the studand'will" be' permitted t snapr back' toi` theiru normal As the studmov'esfarther into' the socket, the fingers 24 will be released and permitted to snap back into contact with the fingers 23. Should an attempt now be made to remove the socket from the stud, it will be necessary to apply sufficient force to flex the fingers 24; outwardly, butvthis can only be doney byJalso flexing the fingers 23 outwardly, which serve as reinforcing elements for tlie'fingers 24, thereby materially increasing the pulling force which must be imparted to the socket in order to disengage the same from the stud.v

Preferably, the stud-retaining element will be inserted in the housing with the fingers 23 againsttheseat 25, although a satisfactory socket-would be produced should the vstudretaining element be inserted yin the reverse position.

The fingers 29 have a double function in. that they not only secure thestud-retaining elementv in the housing,but also serve as limiting stops in determining the position ofy the socket with respect to the article to which it isl attached, as more clearly` indicated in Fig. 8 in which apiece of carpet 's held firmly secured between the fingers 29 andv the spurs 28. The fingers 29 serve as separators whereby the stud-retaining element' is spaced from the under surface ofthe carpet, thereby affording room to receive the stud.

In Fig. l() is illustrated a modified 'form of the invention inwhich two of the fingers 29 of the housing are made of a length substantially equal to its diameter.v -These' fingers of increased length may bebent across the back of the housing` to positions indicated at 29. The endsof'these fingers may extend over andbe supportedby portions of the flange at the opposite sides of the housing. One or more of such fingers bent across the back of the snap fastener-socket will serve as a-satisfactory means of keeping the material of the article, to which the socket is attached, out of the opening intended to receive thestud, and will also serve as a thumb-piece whereby the socket and stud may be pressed into their engaging `relations.

The various features ofthe invention areA so disposed that those of one series bridge the gaps between those of the other series.
